Top Ten Undertale Characters You Would Feel Guilty Killing

Garythesnail
Undertale is an amazing game, and one of its amazing qualities is its cast of characters. You also have the option to spare them all somehow. These are the ones I'd have trouble NOT sparing. I'm not counting Napstablook because you can't actually kill him.

The Top Ten

1PapyrusPapyrus is a character from the 2015 game Undertale, made by Toby Fox . He is the Younger brother of Sans the skeleton, royal guard in training, and a sentry in the town of Snowdin . Opposite to his brother, papyrus is active, loud, and full of himself; but in an endearing way. Papyrus means to become ...read more.

Papyrus is my favorite character in the game, so that in itself makes him a bit difficult to hurt. He also believes that, even in a Genocide Run, you can change and become a better person. It shouldn't be a big surprise that he and Toriel topped the list, because most of the fanbase seems to agree with me on that. - Garythesnail

Papyrus is my favorite character in the game! He's just so nice and friendly and I would hate it if I had to kill him! - Lina1028

I actually choked up when I first saw my friend kill Papyrus. HE'S MY FAVORITE CHARACTER!

Papyrus strikes you as cute when you meet him, he tries to be imitating but fails and he tries to be macho and fails. The way he say NYEH HE HE! Just makes u wanna hug him! The fact he believes in u until u dies adds to that.

2TorielToriel is a main character in Toby Fox's 2016 RPG, Undertale. She is an amazing blend of goat and mother.

Toriel is there with you right from the beginning, and saying goodbye to her is one of the most heart-wrenching moments in the game. Heck, her battle theme is called "Heartache"! I've seen Let's Play gamers kill her and instantly regret it. I teared up the first time I had the goodbye with her AND when I got to her fight on Genocide. - Garythesnail

When you kill toriel she still loves you when I killed her I cried.She wants you to be good. She uses kind words Ben when you tried to leave fighter her and she still loves you. *silence*...That's Just sad!

Even just NOT killing her still makes you sad...

3SansSans or Sans the Skeleton is a character in the 2015 RPG Undertale created by Toby Fox. He is a lazy, pun-loving skeleton who is a supporting protagonist in the "pacifist" and "neutral" routes of Undertale, and a heroic antagonist/final boss of the "genocide" route. He is known for his incredibly difficult ...read more.

After killing him, he says the saddest dialogue in every timeline: "Papyrus, what are you doing here? " Or something like that. Point is, I literally cried after the whole genocide run once I killed sans. That changed my life to see his normally happy personality break, showing his depressed, angry side. I no longer am the person I was after that fight, and I never want to be. It was truly sad.

Sans is-SPOILER ALERT- the final boss of a Genocide route. His death is pretty sad, but what gets him so high on the list is that you've also got the guilt of killing all other enemies before him. His fight is awesome, but it's also guilt-inducing. - Garythesnail

Sans is a really hard boss to beat, so if you're battling Sans or almost about to battle Sans, as Sans would say, you're going to have a bad time. - EpicJake

Please... no...Sans is my favorite!The first time I saw him die, I was in TEARS! I couldn't stop- Sans was THAT important to me! No, I am not a fangirl, I do not claim him, but I do closely love the character in a metaphoric way.

4UndyneUndyne is a main character in Toby Fox's 2016 RPG, Undertale. She is the heroic fishlike captain of the Royal Guard, who takes it upon herself to protect the monsters of the Underground. Her name is derived from the word "Undine", and is a pun on the word "Undying". Her most loved monsters are her mentor, ...read more.

I just saw her Neutral fight. Her death was heartbreaking to watch as she screams that she won't die. It's a lot worse than Genocide.

Her death in all 3 modes is gut-wrenching. In Pacifist, you constantly take away her regenerating health, and in Genocide, you've just killed the only person strong enough to stand a chance against you at that point. Think about that, k? - Garythesnail

5MettatonMettaton is a character in the popular 2015 RPG game, Undertale. He is a robot with a soul built by Dr. Alphys, and is the sole television star of the underground. Mettaton is a popular character in the fanbase. His notable features include his legs, and his catchphrase "OH YESSSS!"

So what do you love the most about Mettaton? For me, I'd have to ask: is "everything" an option? This guy's hilarious! AND he wants to save humanity from Asgore! Why would you WANT to kill him?(to be honest though, his Genocide boss is pitiful) - Garythesnail

6AsgoreAsgore Dreemurr is a boss monster and the king of the monsters in the 2015 RPG Undertale made by Toby Fox. Asgore is the portrayed main antagonist who plans to acquire seven human souls and use their power to break the barrier that seals the monsters underground . Aspects of his character are hinted ...read more.

He's not exactly the most liked character in the fanbase, but Asgore had a kind personality, and was only doing what he thought he had to do for his kingdom. - Garythesnail

A true hero. - Keubab

7TemmieTemmie is minor character from the 2015 game Undertale made by Toby Fox. Made in the likeness of her artist, Temmie Chang, in appearance and character. Both a character and a species of monster, temmies are defined by their mix of cat and dog features, as well as their broken English. Their hidden village ...read more.

I'm not even going to explain this one. WHO DOESN'T LIKE TEMMIE! - Garythesnail

TEMMIE! in the genocide route this is one of the characters I absolutely can not kill

I will kill her any day,she is my least favorite character in the game - Nateawesomeness

8The Greater Dog

It wouldn't seem like much at first, but you basically kill a puppy by doing this. - Garythesnail

I can never do genocide because of this. WHY THE DOGS TOBY WHY - Brobusky

9MuffetMuffet is a character from the game Undertale. She appears in a region called Hotland, selling pastries to raise money to rent a heated limo to help the spider clan from the Ruins (who are also raising a bake sale) reunite with the one in Hotland because the spiders can't cross Snowdin.

Mostly on here for how sad her death scene is. - Garythesnail

It almost made me cry when I killed her and the spider came and gave her a flower! ;_; - HaydenGuyPotato

The part that really got me was when the spider put a flower at the spot where shs was killed. Very sad.

10Lesser DogLesser Dog is a character from Undertale. He is part of the Snowdin Canine Unit, and is famous for his long neck.

He's just a cute little puppy wearing armour!

The Contenders

11FloweyFlowey is a flower in the RPG Undertale. He is the first character you meet, and also your best friend.

Once you hear his backstory in True ending... - Garythesnail

I can't kill him he's so evil and cute and after a floofy goat

12AlphysAlphys is an adorably dorky, lab-coat-wearing, bespectacled, yellow-skinned lizard scientist who resides in her lab in Hotland in the critically acclaimed cult classic RPG known as Undertale, wherein she partakes in the daily act of watching insane amounts of anime and having a vast majority of the ...read more.

Poor girl kills herself.

If you kill everyone but Mettaton, she allegedly commits suicide. Then Undyne hates your guys and Papyrus doesn't know what on earth is going on.

Have fun... - Garythesnail

13BurgerpantsBurgerpants is a vendor in the 2015 RPG video game Undertale, who sells various kinds of fast food working in MTT Resort, such as a hamburger dubbed "Glamburger", ice cream dubbed "Starfait", and even a steak in the shape of Mettaton's, his employer, face.

Can't kill him. I wouldn't even kill him if I had to chance.

14NapstablookNapstablook is a secondary character from Toby Fox's 2016 RPG, Undertale. He is the cousin of Mettaton, who left him in order to become famous. Due to this, poor Blooky has crippling depression.

15Monster Kid

When you hit and kill him he not only whispers he doesn't want to die but he is crying at the same time! - Rayman56

16Shyren

Just... Sad. She could be your singing buddy, but noo!

17Asriel DreemurrAsriel Dreemurr is a character from the 2015 game "Undertale". He was created by Toby Fox. ...read more.
